Hard drives produced for the Northern Hemisphere (for countries like the United States and Canada) are expected to spin clockwise. In the Southern Hemisphere hard drives must compensate for the effects of the spin of the Earth by spinning in counterclockwise motion. "The effects of having an improper spin can be devastating. Lost data, file corruption, and illegal operation errors," says Lloyd Davis of SpinLogic "If you have any concerns, you should quickly return your computer to the manufacturer and ask for a hard drive spin inspection. Your important files might be saved if you act now."
